What is butt welding?

Buttwelding can be an automated or by-hand process, used to attach pieces of metal together. Wrought buttwelding fittings are generally fairly simple; they are designed so that they can be welded directly onto another fitting. With that in mind, however, they need to be developed to certain standards, so they can correctly fit onto other fittings. Types of buttweld fitting can include elbows, caps, tees, reducers, and outlets.

The butt-welding method is the preferred type for commercial purposes since it is more economical, as well as providing a strong fusion of the two metal pieces. Also, it uses the least amount of welding materials and at the same time giving out a strong weld. The automated butt weld process is the more favored process because of its ease of preparation and there is a low chance of adjustments in cases of non-ideal joint preparation because of the absence of human guidance. It is expected that butt welds have the strongest welds with the least amount of imperfections.

Advantages of Butt Welding

There are several advantages of butt welding among these are:

The ANSI / ASME B16.9 buttwelding fittings assure of its permanent leak proof quality and strength.

Having a continuous steel structure between the pipes and fittings gives the piping system better strength.

The pipe fittings when used using this method gives out a smooth surface and a gradual directional changes thus making it decrease the pressure losses, the turbulence of the system and protecting it from corrosion and erosion.

This method is more economical, which does not hurt the budget.

Butt welding joints also offer smaller space in the system.

A weld can be made using this method in a wide range of sizes and complex shapes although both ends should be equally matching.

ASME B16.9 Seamless Weld Fittings can be used in a wide range of materials such as steels, stainless steel, aluminum alloys, nickel alloys or titanium.

Solidification cracking and porosity is usually not an issue.

The butt welding process can be automatic or semi-automatic and monitoring of the welding process can already indicate the quality of the work.
